Indicated for the diagnosis of adult growth hormone deficiency (AGHD).
FDA Label
This medicinal product is for diagnostic use only. GHRYVELIN is indicated for the diagnosis of growth hormone deficiency (GHD) in adults.
Diagnosis of growth hormone deficiency
Maximum GH levels from stimulation are observed between 30 to 90 minutes after administration of macimorelin. Increase in the QTcF interval may be observed from macimorelin administration.

V04CD06 - Macimorelin
Absorption
Macimorelin is a novel, synthetic ghrelin agonist, which is readily absorbed from the gastrointestinal tract. The maximum plasma concentration (Cmax) was observed between 0.5 and 1.5 hours following oral administration of 0.5mg/kg macimorelin to patients with AGHD under fasting for at least 8 hours. Higher doses of drug demonstrate a dose-proportional increase in plasma concentrations. A liquid meal decreased the macimorelin Cmax and AUC by 55% and 49%, respectively.
Volume of Distribution
Following a single oral dose of 0.5 mg/kg macimorelin, the mean volume of distribution of the central compartment is 5,733.4 565.7L.
Clearance
Following a single oral dose of 0.5 mg/kg macimorelin, the mean clearance over the fraction absorbed (Cl/F) was 37,411.0 4,554.6 mL/min.
Macimorelin predominantly undergoes CYP3A4-mediated metabolism according to an *in vitro* human liver microsomes study.
The mean terminal half-life (T1/2) is 4.1 hours following administration of a single oral dose of 0.5 mg macimorelin/kg body weight in healthy subjects.
Ghrelin is an endogenous ligand for the GH secretagogue receptor that is also called the ghrelin receptor (GHS-R1a). Upon activation of the receptor, ghrelin serves to increase growth hormone (GH) secretion. Macimorelin mimics the actions of ghrelin by stimulating GH release. As a synthetic agonist, it activates growth hormone secretagogue receptors present in the pituitary and hypothalamus.
